Double-antibody sandwich method for determination of 2 price or value of more than two macromolecular antigen, but not for the determination of haptens and small molecules unit antigens, because of two points can not form the sandwich.

双抗体夹心法适用于测定二价或二价以上的大分子抗原，但不适用于测定半抗原及小分子单价抗原，因其不能形成两位点夹心。

The feasibility of determining the pentosan in pre-extraction liquor from eucalyptus chips by using Douglas colorimetric method was discussed in this paper. The visible spectrums of xylose, glucose, mannose, galactose and kraft lignin were compared under the same color reaction conditions. The results showed that the disturbance from hexoses and lignin can be eliminated when the pentosan is identified and determined by the maximal absorption at 553nm.

摘 要：探讨了 Douglas 比色法用于测定桉木半纤维素预提取液中戊聚糖的可行性，通过对木糖、葡萄糖、甘露糖、半乳糖和木素在相同条件下显色反应后的谱图进行比较，证明利用553 nm 处的最大吸收进行测定可以排除己糖和木素的干扰。

Through tests on the determination of interference from the sample color, not only is its interference eliminated but also the accuracy of the method improved.

培酸法适用于深色溶液分析，灵敏度和准确度较高，通常用于总钒的仲裁分析；但是该法只适用于测定总钒，四价钒与五价钒只能用其它方法测定，这样就会引入方法误差，使四价钒、五价钒与总钒不匹配。

The uncertainty for determination of iron concentration in zinc-iron coating of galvaneal by chemical method was evaluated.

对用化学法测定锌铁合金钢板镀层铁含量测量结果的不确定度进行评定，分析了该方法测定过程的不确定

The results show that the maximum CLA content is 15.4 g CLA per 100 g isomerized rapeseed oil and the characteristic peaks of CLA in CLA standard as well as isomerized rapeseed oil are found at 234 nm at 25 ℃. A linear regression equation is obtained.

4g，利用紫外分光光度法测定的共轭亚油酸标准品和异构化菜油在25℃条件下的最大特征吸收峰波长为234nm，并建立了线性回归方程，因此，只要测定油样在234nm的吸光度再依此方程可算得油样中共轭亚油酸的浓度。

采用后一种方法测定的凋落物分解率可以解决尼龙网袋法测定分解速率结果偏低的问题。

Rresults from those studies can be summariazed as follow:(1) A preliminary study no correlationship between the UV-VIS reflection spectrum of tomato fruit surface and the lycopene amount of tomato fruit was undertaken. Based on observation from this study, a damage-free and in-situ detection technique of lycopene amount from tomato was developed with UV-VIS reflection spectroscopy;(2) The geometrical isomers of lycopene were separated successfully on C30-HPLC-PDA-ELSD. The absorption coefficients of Z-isomers were consequently dedermined. The geometrical isomer composition of lycopene could therefore be assessed. Those efforts formed a solid base to identify the natural product from synthetic compound of lycopene;(3) Lycopene resource from the fruit of Autumn oliver was proved to be available for industrial application. An extraction methos of lycopene from the fruit of Autumn oliver by supercritical carbon dioxide was developed at laboratory scale;(4) A method to extract lycopene by supercritical liquid with improved efficiency was developed; Data from this investigation suggested that a proper raw material pre-extraction process was important for a better extraction efficiency;(5) Variation in the geometrical isomer composition of lycopene during its metabolish in rat was assessed. A large amount of Z-isomers were observed. This variation took place in serum;(6) The absorption rate and accumulation in serum of natural lycopene in rat were assessed;(7) Ability to quench singlet oxygen by different geometrical isomers of lycopene was compared;(8) It was detected that whether natural lycopene had functions to regule blood-lipids and LDL antioxidation;(9) A C31 degradation piece of lycopene was found in the prostate gland of rat.
